盈锋钻尾钉成型过程你了解吗

钻尾钉，顾名思义，即可以实现自攻自钻性能的螺钉，与我们常见的螺钉相比，它的优势在于：①更适合对紧固要求较高的安装场景；②不需人工开孔而能快速实现板面攻入、紧固作用；③极大程度简化安装步骤，节省时间与人力成本。要了解钻尾钉，就不得不从源头讲起：它是如何生产的呢？

Self-drilling nails, as the name suggests, are screws that achieve self-tapping and self-drilling performance.Compared with our common screws, its advantages are: ①it is more suitable for installation scenarios with high tightening requirements；②can quickly realize the plate surface penetration and fastening without manual opening；③greatly simplifying the installation steps and saving time and labor costs.To understand the self-drilling nail, we have to start from the source: how is it produced?

一.原料购入与检验/Raw material procurement and testing

线材购入及其质量把控是正式生产前的重要一环，原料进厂后，盈锋质量控制部门会安排人员取样，对照材质单进行原料检验，检验合格后放置于原料合格区域。盈锋螺钉常用线材材质包括：碳钢、304、316、435等。

After the raw materials enter the factory, the quality control department of Infastech will arrange personnel to take samples, check the raw materials against the material list, and place them in the qualified area of the raw materials after passing the inspection.The commonly used wire materials of Infastech screws include: carbon steel, 304, 316, 435, etc.

二.合格原料投入生产/Raw materials are put into production

原料投入生产后，共经历3道工序的打磨：冷镦、夹尾、搓丝才能最终成型。冷镦，也称打头，是冷镦机利用一模二冲等模具锻造线材而使线材头部成型的工序。生产前，工作人员会依照生产订单选取合适线材，由抽线设备将线材送入冷镦机，螺钉成型之旅就此开启。盈锋常见头型有：外六角、内梅花、十字槽（含平头、沉头、盘头）等。

After the raw materials are put into production, they go through three grinding processes: cold heading, tail clamping, and thread rolling.Cold heading, also known as heading, is a process in which a cold heading machine uses different molds to forge wire to form the wire head. Before production, the staff will select the appropriate wire according to the production order, and the wire drawing equipment will send the wire into the cold heading machine, and the screw forming journey will begin.Common head types are: hexagon, inner torx, Phillips (flat head, countersunk head, pan head) and so on.

夹尾，夹尾机利用钻尾模具对冷镦后的物料施加压力使其尾部成型的工序，也是钻尾钉与自攻钉形成差异的重要一步，这一步需严格把控生产物料同心度、刀刃宽度等各项参数。盈锋常见的钻尾如下图所示。

The process of applying pressure to the material after cold heading to form the tail is also an important step in the formation of the difference between the drill tail nail and the self-tapping nail. This step requires strict control of the concentricity of the production material, the width of the blade and other parameters.

搓丝，即形成螺纹的工序，2块牙板分别在固定、滚动的相对运动作用下使物料塑性变形，从而形成螺纹。搓丝工序结束，钻尾钉也就成型了。

Thread rolling, that is, the process of forming threads, two tooth plates are plastically deformed by the relative movement of fixation and rolling respectively, so as to form threads.

综上所述，盈锋钻尾钉经历冷镦、夹尾、搓丝3道工序才最终成型，可谓”千磨万击还坚劲“。螺钉人也当如此，我们应在拓展建筑螺钉服务蓝图的道路上不惧打磨、昂首向前。

To sum up, Infasron drill nails go through three processes: cold heading, tail clamping, and  thread rolling before they are finally formed, which can be described as 'thousands of grinds and strength'. The same should be true for screw people, we should not be afraid to polish and move forward on the road of expanding the blueprint of construction screw services.
